Triggering builds from CI

Learn how to trigger builds on EAS for your app from a CI environment such as GitHub Action and more.

This document outlines how to trigger builds on EAS for your app from a CI environment such as GitHub Actions, Travis CI, and more.

Before building with EAS on CI, we need to install and configure eas-cli. Then, we can trigger new builds with the eas build command.

Prerequisites

Run a successful build from your local machine

To trigger EAS builds from a CI environment, we first need to configure our app for EAS Build and successfully run a build from our local machine for each platform that we'd like to support on CI.

If you have run eas build -p [all|ios|android] successfully before, then you can continue.

If you haven't done this yet, please refer to the Creating your first build guide and return here when you're ready.

Configure your app for CI

Provide a personal access token to authenticate with your Expo account on CI

Next, we need to ensure that we can authenticate ourselves on CI as the owner of the app. This is possible by storing a personal access token in the EXPO_TOKEN environment variable in the CI settings.

See the guide for personal access tokens to learn how to create access tokens.

(Optional) Provide an ASC Api Token for your Apple Team

In the event your iOS credentials need to be repaired, we will need an ASC API key to authenticate ourselves to Apple in CI. A common case is when your provisioning profile needs to be re-signed.

You will need to create an API Key. Next, you will need to gather information about your Apple Team.

Using the information you've gathered, pass it into the build command through environment variables. You will need to pass in the following:

• EXPO_ASC_API_KEY_PATH: the path to your ASC API Key .p8 file, e.g. /path/to/key/AuthKey_SFB993FB5F.p8
• EXPO_ASC_KEY_ID: the key ID of your ASC API Key, e.g. SFB993FB5F.
• EXPO_ASC_ISSUER_ID: the issuer ID of your ASC API Key, e.g. f9675cff-f45d-4116-bd2c-2372142cee09.
• EXPO_APPLE_TEAM_ID: your Apple Team ID, e.g. 77KQ969CHE.
• EXPO_APPLE_TEAM_TYPE: your Apple Team Type. Valid types are IN_HOUSE, COMPANY_OR_ORGANIZATION, or INDIVIDUAL.

Trigger new builds

Now that we're authenticated with Expo CLI, we can create the build step.

To trigger new builds, we will add this script to our configuration:

npx eas-cli build --platform all --non-interactive

This will trigger a new build on EAS and print the URLs for the built files after the build completes.
